La córnea es la capa transparente en la parte frontal del ojo. Protege su ojo del polvo y los gérmenes y ayuda a filtrar los dañinos rayos ultravioletas, o UV. La córnea también ayuda a enfocar la luz que entra a su ojo. La córnea está hecha de proteínas fuertes, pero puede lastimarse. Una cortadura o un rasguño leves, llamados abrasiones, suelen ser algo menor. Pero una abrasión fuerte o una punción en la córnea pueden ser cosas muy graves, y pueden afectarle la visión. Constituyen emergencias médicas.

Convergence insufficiency (CI) is a problem with the way the eye moves. It makes it hard to focus on things nearby. When the eyes converge, it means they point inward (toward the midline) to focus on something close. With CI, the eyes have trouble doing this. One eye may turn out instead of looking inward. CI can cause blurred vision, double vision, and eyestrain.
